Question

Which expression represents 5 less than a number?

a)5 – n
b)5 • n
c)n – 5
d)-n – n – n – n – n

Answer 1

C) n-5

I only know how to explain it using a realish scenario

So let’s pretend that we know the value of n

That “number” will in this case be 10

Now the question states: Which expression represents 5 less than 10

We know that the words “less than” really will turn into a subtraction sign(-)

Knowing all of this, we can write 5 less than the number 10

This will be 10-5

But, since I’m this actual equation we don’t know the value of n, it will remain n-5

Hope this helps comment below for more questions:)

Answer 2

C) n - 5

Explanation:

In this situation, n is the number in-which 5 is less than.

So n - 5 proves this because it means a number (n) is less than 5
